The U.S. FDA cleared Alivecor Inc.'s Kardia AI V2 interpretive electrocardiogram (ECG) algorithm for use in its personal ECG app and devices. Currently, the Kardia line permits consumers to take a 30-second medical grade ECG at home and instantly see whether they are exhibiting symptoms of atrial fibrillation, bradycardia, tachycardia or have normal heart rhythm.
